I have downloaded several copies of a video I'm trying to watch, but VLC won't show the video or play the sound. You can see the file playiing from the controller but nothing happens. I have also tried to play these files in QT 7 along with the several plugins I have such as 3ivx and Divx. QT just shows a still screen with color bars. Can anyone tell me what causes these problems with an AVI file??
